  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

    SEO Web Vitals

    What are SEO Web Vitals ?

    Web Vitals are made up of a number of important metrics, such as your website’s page speed and loading performance, these metrics all play an important role in search engine optimisation. 

    The more technical terms for these metrics are Page Speed Score, First Contentful Paint (FCP), Final Input Delay (FID), Last Contentful Paint (LCP) and Cumulative Layout Shift (CLS).

    Why should you use SEO Web Vitals ?

    SEO Web Vitals are being used more and more by search engines such as Google to rank websites so they help ensure a great page experience for users who arrive via links from their search results. 

    By monitoring your SEO Web Vitals you can see how good or bad a single page performs and then prioritise the optimisation of strategically important pages to help improve the ranking position within search engine results.

    For ease of use you can receive regular reports in your email inbox and you can configure custom alerts to automatically notify you when a page score changes significantly. This saves time by not having to check page performance scores manually while ensuring you will be notified should there be any important change that needs to be actioned.

    You should use SEO Web Vitals to understand how your site performance is impacting your overall visitor experience.

    Four key benefits of using SEO Web Vitals :

    Improve your search result rankings

    Matomo SEO Web Vitals FAQs

  • FFMPEG : audio unsynchronized, losing framerate and strange behavior when pavucontrol is open

    10 mars 2021, par Rik Ferreira

    I'm trying to record my desktop screen with internal audio and mic, but I'm noticing some issues with the output, according to this empirical scale :

    


      

    • If I record only the desktop, the output is GOOD.
    • 


    • If I record the desktop + mic, the output is GOOD.
    • 


    • If I record the desktop + internal audio only, the output is BAD.
    • 


    • If I record the desktop + mic + internal audio, the output is BAD.
    • 


    • If I record the desktop + mic + internal audio + open pavucontrol, the output is GOOD.
    • 


    


    Good means the two audio sources and the video are acceptably synchronized and bad means not synchronized at all.

    


    I recorded some samples to show what is going on :

    


    


    I'm snapping my fingers near the microphone when the Beep! message appears along with the sound.

    


    I'm using a simple script to play a sound and show a message in the terminal instead of using pavucontrol because it masks the problem.

    


    FFMPEG call

    


    Although the entire script is visible in the videos, here is the ffmpeg call in plain text :

    


    Dual audio

    


    ffmpeg -y \
    -f x11grab -s 1920x1080 -i :0.0 \
    -f pulse -i 0 \
    -f pulse -i 1 \
    -filter_complex amix=inputs=2 \
    output.mp4


    


    Only microphone

    


    ffmpeg -y \
    -f x11grab -s 1920x1080 -i :0.0 \
    -f pulse -i 1 \
    output.mp4


    


    Other info

    


    SO : Arch Linux

    


    When pavucontrol isn't open, pacmd list-source-outputs returns : 0 source output(s) available., but when pavucontrol is open :

    


    pacmd list-source-outputs | grep source

2 source output(s) available.
        source: 0 
                module-stream-restore.id = "source-output-by-application-id:org.PulseAudio.pavucontrol"
        source: 1 
                module-stream-restore.id = "source-output-by-application-id:org.PulseAudio.pavucontrol"


    


    What am I missing ? Why the ffmpeg works fine when pavucontrol is open ?
